Improvement of quality of details at round grinding in the conditions of a floating workshop

Abstract

The results of laboratory studies of the grinding processing process are given taking into account the evaluation of the quality of the surfaces of the shafts with disturbing vibrational influences on the equipment of external forces that are the consequence of sea waves, as well as the neighboring operating equipment in a floating workshop. To determine the influence of external influences on the quality of processing during grinding, an experimental stand was used, including a cylindrical grinding machine with a complex of test equipment, as well as a compressor placed at a different distance from the machine, creating external vibration effects simulating external disturbances through the surface Floor and foundation on the machine bed, corresponding to the effects of the external environment and the operating neighboring equipment. The dependences of the frequency of mechanical oscillations (in the measuring zones-the base-bed and the machine table guides in the transverse and vertical directions) are obtained, the amplitude of the vibro-displacement in these zones from the conditions of the circular grinding machine and sea-wave levels. The changes in the error in the shape of the machined parts, the roughness of the machined surface, the waviness of the roll neck surfaces according to the basic and achieved variants are determined taking into account the use of new designs of effective vibration isolating supports and devices.
